Harvey has only been projectable for about 24 hours or so ahead due to the Virgin stall and roll path... About mid Sunday or earlier it started becoming clearer in the path for the turn back into toward Houston again for 3rd landfall... How the bands of heavy rain came down over 100 miles East of Harvey and over Houston area primarily was a very tough thing to predict... But knowing where the water is now and where Harvey heads again is better known... Precaution now seems obvious... Moving people into sturdy, large buildings on 3rd floor or higher is also something to consider with shelter in place... Have to move people already saved thru tough rescues to safe havens against further potential... Don't look...another wave blooming overnight in the Central Atlantic that isn't even being watched yet... Harvey just spawned fast under Ideal conditions that are always in the Gulf during late summer...LJ
